I know I've seen a thread on the site somewhere that talked about the effects of heat buildup (or cold weather) on a gun stored in a car. I tried searching the forums and could not find it. Any suggestions? Links?

My concern is that my employer does not allow carry on the premises. I have to store my (polymer) gun in the vehicle. Hot weather can get car interior well over 120-130 degF. Of course, cold weather can get as low as the current conditions. How does heat/cold in the vehicle affect the gun and the ammo? How does cycling the temperature of the gun from normal room temperature to the extremes every day affect it?

Wouldn't worry about it unless you are getting condensation on it. The only thing 130 degrees might affect is the lube depending on what you use.

Cars cant get hot enough to affect a gun other than drying light gun oils out over the course of the day.

Temperature has an effect on ammunition in that hotter temps increases chamber pressure colder can make some powders difficult to ignite. Its one reason i dont like +p or +p+ type ammo as they tend to be getting close to dangerous pressure levels. Especially stuff like buffalo bore brand.

Early glocks had issues with extreme heat and cold. No current production xd/m glock ruger sw etc have issues with heat or cold. Some super cheap poly guns might but im not aware of any.

I keep my carry gun in the center console while at work. No idea how prolonged heating-cooling affects ammo as i shoot the old and buy new sd rounds at least once a year.

I have a Nano car vault I leave my firearm in when going to work at airport. Hope this helps.

Awesome! Checked out several other reviews of these vaults. All were thumbs up. Ordered one online tonight. Thanks! And thanks for your service, sir!

Same issue with my employer and have kept either my 38 or my Ruger 8 mm in the center console for years without any problems. And I am in Florida. I also shoot up my personal defense ammo about once a year. What a good idea, it is about a year, I better go shoot!

You're mighty welcome! :)
Got it today. Took all of 5 minutes to install it. I'm always nervous about getting involved with a dashboard. This time not a single hiccup. Used to worry about leaving the gun in the car. Now I don't have to worry. Hoistin' a Sam Adams in your honor as we speak!

I leave my 1911 and my bersa .380 in my truck for long periods of time without any trouble with ammo or the weapon.

I have noticed that when i leave my 870 or NEF pump in the truck for more than a week it starts to develop some surface rust which is easily removed with a rag with gun oil on it.

If our military can store, operate and fight with arms and munitions packed in their humvees all day in the blazing desert heat, I'm confident my gear will perform.
I agree with you here. I live in Az where the temp is currently 108. I have stored my rifle, mag's, pistol and a bailout bag in my truck for over 20 yrs and have never had a problem with any of them. Short of changing out the ammo every couple of years and the mre's everything is the same.

One thing you might think of is putting the little pouches you get out of your new shoes in your carry bag to help moisture build up. Been doing that for years, wife thinks I am crazy but that is nothing new.

Here in Tulsa it's been over 100 (104-105) for several days now. Heat buildup in a closed car is impressive. When I leave work and reholster my gun, the thing is too hot to handle. If I had to defend myself with it at that moment, I'd probably only get a couple shots off before having to drop it! Even if the gun and ammo are OK, my hand isn't! I'll have to work on reducing the heat buildup. Reflecting screens, crack the windows, etc.

Sorry about reviving an old thread, but this is the season for the other half of the discussion, cold. (Yes C3, I did see your post about Fairbanks...) Just wanted to say, Brrrrrrr.... reholstering a gun in sub-freezing weather is like strapping on an ice pack. Another fine reason to open carry. I don't even want to think about sticking that thing IWB!!! :eek:
